Splurge Or Save...

With summer coming I really need to sort out a pair of sunglasses...Ive had my eye on a pair of Ray Ban Wayfarers or Dylans for a while now and am wondering whether this summer I should just bite the bullet and go for it or get another pair of knock offs at a festival...break them...and buy another pair... what do you think??
My faves are these...

Dylan in gun metal blue...would literally go with everything...
Wayfarer in Coral Red...my usual go to festival sunglasses...
Or these Clubmasters in green...
There are just so many I like which makes me think I shouldnt just splash out on one pair as Ill probably see another pair I like a week later but it would be good to have a good solid pair to last me the summer...decisions decisions...
